' Application filed march 17,1922. Serial No. 54 4 ,532.

v To all whom it may concern iBe it known that I, FRANK J. LIEsKn, a citizen of the United States, residing at Detroit, county of Wayne, State ofMichigan, have invented a certain new and useful Improvement. in Lamp-Shade Supports, and

declare the "following to be a full, clear, and

exact description ofthe same, such as will enable others skilled in the art to which it pertains to make and use the Sarina-reference being had to the accompanying drawings,

which form apart of this specification. This invention relates to lamp shade supports and the-object of the invention is to provide a lamp shade support which may be easily connected to the usual electric light socket, a cover being also provided for the electric light socket whichis utilizable in combination with the lamp shade support. A further object of the invention is to provide a means for supporting a lamp shade on the usual electric light socket so that the shade may be easily secured to or removed from the socket quickly and without dithculty. Another object of the invention is to provide a: hoodor cover for the electric light socket which also covers the lamp shade support and may be quickly secured to or removed from thesooket. A further object of the invention is to provide a pair of threaded members adapted to be easily secured to the exterior of the socket and a pair onto which the interthreading membersfor socket showing the manner of securing the two threaded members thereto.

Fig. 4 is a perspective View of the interthreaded members adapted to be secured to the socket. i i

v Fig. 5 is a perspective View of the outer threaded.member'adapted to be secured'to the lower end 01"? the lamp socket.

Fig. 6 is a perspective'view of the interthreaded members adapted to be clamped to the lamp shade. r

Fig. 7 is a section therethrough.

Fig. 8 is a section through the lamp. shade and support showing an alternativetype of construction.

Fig. 1 shows an electric lampfsocketl of the usual construction provided with a key 4: for operating the same. The socket shell '1 is provided with a threaded portion on the interior into which the incandescent bulb 5 may 'bethreaded and the socket shell 1 is provided with a circumferential head-- or rib 2, as shown in Figs. 1 and 2. As shown in Figs. 3 and 4 a threaded sheet metal" member 7 is provided having two heads 8 and 9 the head 8 being adapted to he slipped over the head 2 of the socket and the bead'9 be ing knurled for a purpose hereinafter de scribed. This member 7 is provided with a series of slots 10 so that the beads Sand 9 may be sprung out toengage over the head 2'. At this time a threaded member 12 is threaded over the member 7 as shown in Fig. 3 and the member 12 is provided with a knurled head 13 for turningthe same. The

threading of the member. 12 on the member 7 draws the bead 8 of the member 7 into tight engagement with the bead 2 thus'securing the threaded members 7 and '12 to the'socket,

the member 7 being held from turning by gripping the knurled bead 9 whilethe member 12 is threaded thereon by means oi -the V knurled bead 13. The lamp shade6 is-usually formed of glass and is provided'with a return bent flange 25 atfthe upper end which is usually, adapted for securing the shade'jn the normal. type of holder. A member 15 is provided as shown in Figs. 1, '6 and 7 having a series of apertures 18 therein to allow heat to escape from the lamp shade andthe a dependingfiange 17 adapted to engage over the flange'25 of the lamp shade as shown in Fig. 1, the member 15 being of sheet metal and provided I with threads as shown.

A sheet metal member 19 is provided. with pcrtures 22 therethrough for the escape of heat from the lamp shade and the member 19 is provided with an annular shoulder terminating in an outwardly extending flange 21 adapted to engage against the shoulder 23 of the lamp shade as shown in 1, the member 19 being made of .a dimaster to fit any of the standard lamp shades. The member 19 is provided with a central cyliadrical threaded portion formed of sheet metal and adapted to be threaded over the threaded portion of the member 15 as shown in Figs. 1, 2 and 7. By threading these members 15 and 19 together the lamp shade is hndingly secured between the flange 16 of the member 15 and the flange 21 of the mem- 1 i9. The, threaded member 15 is also inally threaded and when the lamp shade d members 15 and 19 are assembled'tot .ner as shown the member 15 is threaded Un -CO the member 12 which is secured to the electric light. socket, the knurled head 13 of the member 12 limiting the threading otthe interthreaded members 15 and 19 thereon. By means of the apertures 18 and 22 of the members 15 and 19 the heat from the bulb 5 may pass upwardly through the space 2 1 struction shown a solid support is provided for the lamp shade on the socket and the lamp shade may, be easily removed from the socket 1 1, and, should the shade become, broken the interthreading members 15 and 19 may be unthreaded'to allow the support to be secured to a new lamp shade.

In Fig. 2 a cover 27 for the socket is shown having a slot 28 which is moved over the key 1 of the socket and the ring 33 be unthreaded from the upper end of the socket and inserted through the aperture 34: of the cover 27 and threaded back in place to bindingly secure the cover to the socket. The cover at the upper end is provided with a flat raised portion 29 provided with a series of apertures therein so that heat may pass upwardly from the lamp shade support through the space 35 about the socket and thence outwardly through the apertures. 30. At the the parts are hidden from view by-the cover which is the only part that needs finishing. An alternative form of construction is shown in Fig. 8 in which the lamp shade 6 and interthreading members 15 and19 clamped theretoare utilized.v In this case the threaded members 7 and 12 are d1s-,

pensed with and the lower endor the socket 1 is provided with'threads 3 formed therein and a circumferential bead 2 is-provided immediately above the threads 3 to limit the threading of the interthreaded memers 15 and 19thereon. is somewhat cheaper than that shown in Fig. 1 and at the same time has all the advantages thereof.- With this'device the interthreading members 15 and 19 are This construction threaded together to engage the lamp tion, its utility and mode of operation, what.

I claim and desire to secure by Letters Patento'f the United States is 7 1. The combination with an electric light socket having a circumferential bead, of a threaded sheet metal member having a bead at the upper edge and adapted to be sprung over the bead of the socket, a sec- 0nd threaded member for contracting and maintaining the first member on the socket, said second member having aknurled bead providing a shoulder at the upper end, an annular member threaded on said second member seating against the bead and havflanges providing a meansfor supporting a lamp shade. I

2. The combination with an electric light socket, of a threaded member secured thereon and provided with a lateral flange and a peripheral depending flange substantially at a right angle thereto, a second member having a lateral flange of substantially the same diameter as the depending flange, and being in threaded relation withlthe first member, and a lamp-shade having the upper end fitting within the peripheral flange of the first member and having a shoulder engaged on the interior bythefiange of the second membenthe two members together providing the sole support for the shade.

In testimony whereof, I sign this specification.

FRANK J LIESKE.
